Flexible Online Task Assignment in Real-Time Spatial Data
Summary: Defines Flexible Two-sided Online task Assignment (FTOA) for real-time spatial data, guiding idle workers via predicted task/worker distributions to boost matches. Two-step framework combines offline prediction with POLAR-OP online assignment; achieves 0.47-competitive ratio and O(1) per-event processing, validated on synthetic and real taxi data.
